The legal precedent is that encryption is a munition in the United States, and therefore protected by the Second Amendment.
Don't confuse people here, there is no such precedent.
Bitcoin is a digital currency. It's not a weapon, it's not a free speech mechanism. There's absolutely no way that any court would deem that Bitcoin is protected within the First or the Second amendment. If the US government has a precedent of seizing gold, why would it recognize the right to own Bitcoin as a part of the Constitution?
I dont mean to confuse anyone. This is not my analysis. The weapon position is from someone named Jason Lowery who works for the US Space Force. I do believe Bitcoin falls under speech because we have a 12 word seed phrase that gives us access to our property. Nobody can say we are not allowed to keep those 12 words in our head, speak those words, or write them down.
